In addition to the usual supermarket selection, this "king of the lowest prices" supermarket offers exotic staples from all over the world. International products include innumerable varieties of rice (jasmine, Thai, fragrant shrimp), available in big bags; a huge range of spices, hot sauces and jalapenos; South American juices; coconut milk; Spanish coffee; plantains; flavored tapioca; frozen banana leaves; and Mexican chocolate syrup to name a few. "Institutional sizes" for items such as mayonnaise are stacked beside regular shelves. Extra Supermarket quite possibly has the largest selection of corn oil in Essex county.
Extra Supermarket has "Cash Express" for check cashing and bill paying.
